Ruihua Technology: Application of Release Films in Automotive Glass

As automotive intelligence and personalization demands grow, smart dimming glass (e.g., PDLC liquid crystal glass) has gained widespread adoption in sunroofs, side windows, and in-vehicle displays due to its switchable light transmittance. Its manufacturing requires precise integration of liquid crystal materials and glass in high-precision environments. Ruihua Technology’s release films, leveraging unique properties, have become a critical material in this process, enhancing production efficiency and product reliability.

Core Applications: Key Protective Layer in Smart Dimming Glass Manufacturing

1. Precision Lamination Protection

• During high-temperature lamination of liquid crystal films and glass substrates, Ruihua’s release films act as temporary protective layers, isolating environmental contaminants and preventing oxidation or structural damage caused by heat.

• Their low surface energy ensures uniform distribution of liquid crystal molecules, eliminating bubbles or optical defects to guarantee visual clarity.

2. Clean Release & Anti-Interference Performance

• Proprietary coating technology enables nearly residue-free peeling, meeting automotive glass’s stringent requirements for high transparency and low haze.

• Anti-static design minimizes dust adhesion during production, reducing cleanroom maintenance costs and avoiding interference with surface-mounted electronics (e.g., vehicle sensors).

3. Adaptability to Complex Curved Surfaces

• High flexibility allows tight conformity to curved or irregular glass surfaces, supporting cold bending processes for large-curvature glass (e.g., panoramic sunroofs) while preventing stress damage in bent areas.

• Enables high-precision cutting processes to enhance efficiency and yield for irregularly shaped glass.

Technical Advantages

• High-Temperature Stability: Maintains physical integrity under extreme heat, avoiding defects caused by deformation in traditional materials.

• Broad Process Compatibility: Applicable to multiple dimming glass technologies (e.g., PDLC, EC electrochromic glass), simplifying production line transitions.

• Eco-Friendly Design: Silicone-free formula complies with automotive industry sustainability standards and supports material recycling.

Customer Value

• Improved Yield: Reduces protective film waste and glass scrap rates, lowering overall costs.

• Enhanced Reliability: Ensures long-term performance without delamination or discoloration, compatible with ADAS and other high-precision automotive systems.

• Accelerated Innovation: Enables advanced designs like curved glass and ultra-thin dimming modules, driving automotive glass innovation.
